Plain-English summary
A 73-year-old woman had a rare type of internal hernia called an arcuate line hernia, where parts of her intestines pushed through a weak spot in her abdominal wall. She experienced occasional pain in her lower left abdomen, and doctors used a special imaging test to confirm the hernia and found she also had an umbilical hernia. They performed a minimally invasive surgery to repair both hernias using a mesh material to cover the weak areas. After the surgery, she recovered well and was able to go home three days later, remaining free of symptoms for a year afterward. This case is notable because it is the first time this type of hernia has been repaired using this specific surgical technique.
Abstract
Arcuate line hernia (ALH) is a rare internal hernia in which abdominal contents protrude into the retrorectus space through a defect between the arcuate line and rectus abdominis. Because the bulge lies behind the rectus abdominis muscles, symptoms are often non-specific, making diagnosis difficult. A 73-year-old woman presented with intermittent left lower abdominal pain. Thin-slice prone computed tomography obtained during the Valsalva maneuver demonstrated small bowel herniation through the left arcuate line, consistent with ALH, along with a concomitant umbilical hernia. Laparoscopic intraperitoneal onlay mesh (IPOM) repair was performed using a composite mesh covering both defects with adequate overlap, secured with transfascial sutures and absorbable tacks. The postoperative course was uneventful; the patient was discharged on postoperative Day 3 and remained symptom-free without recurrence at 1 year. To our knowledge, this is the first reported case of ALH with a concurrent umbilical hernia repaired laparoscopically using the IPOM technique.
